Abstract: In a data storage system providing access to a production dataset and snapshot copies of the production dataset, a production meta bit map identifies blocks of storage that are invalid in the production dataset. If a block in the production dataset is invalid when a snapshot copy is being made, then there is no need to copy the block to storage for the snapshot before writing to the block. Moreover, if a block in the production dataset supporting a snapshot copy is dynamically invalidated, it may be kept in the production dataset until it is written to. For this purpose, a respective snapshot copy of the meta bit map is made and kept with each of the snapshot datasets, and the snapshot copies of the meta bit map are merged in order to indicate the blocks that are invalid for all of the snapshots.

Abstract: Time stamps in an encoded digital motion video data stream (such as an MPEG Transport Stream) are re-stamped for seamless splicing. The re-stamping includes attainment of Presentation Time Stamp (PTS) agreement in the video stream, alignment of audio stream and video stream Presentation Time Stamps, and re-stamping of the Program Clock Reference (PCR) to eliminate jitter and to comply with MPEG standards. The MPEG compliance is achieved by padding, stuffing and insertion of freeze B and P frames and pre-encoded black I frames. Freeze frame insertion can be also achieved by replacing B and P frames by, smaller in size, freeze B and P frames respectively. No frames are discarded such that both spatial and temporal frame accuracy (no extra frame insertion assumed) is achieved.

Abstract: A bicycle carrier adapted to be mounted on the rear of a vehicle. The carrier comprises first and second mounting members and a pair of horizontally spaced bicycle supporting arms connected to the mounting members. The mounting members are pivotably connected for relative rotation about a horizontal pivot axis between a plurality of adjusted positions. The carrier includes indicia corresponding to each of the adjusted positions of the mounting members, so that a user can quickly return the carrier to the same adjusted position. The supporting arms carry cradles formed of an elastic material for receiving a bicycle. Each cradle includes a curved supporting surface for receiving a bar of the bicycle frame, and an integral strap which can be extended over the bar to retain the bar within the cradle. An anti-sway bar hangs downwardly from at least one of the supporting arms for resisting swinging movement of a bicycle.
